IMPROVEMENT |N- Pom-ABLE MACHINERY FoR PLANING METALS.

Specification forming part of Letters Patent No. 5,301', dated September 18 1847.

To @ZZ whom t may concern.-

Be it known that I, ALFRED C. JONES, engineer and machinist, of the city of New Orleans, in the State of Louisiana; have invented a new and useful Portable Machine for Planing Metals; and I do hereby declare that the following is a full and exact description thereof.

The machine forthe planing of metals is an instrument now well known in every good machine-shop, and is one of the most valuable of the tools used by the machinist. It is not adapted, however, to the operating upon small work, and is from its nature a fixture to which the article to be operated upon must be carried and affixed, and such is the arrangement of its parts that it cannot by a mere reduction of sizel be rendered portable, so as to adapt it to the advantageous working of such pieces asit is intended to work by my improved portable instrument, andthe consequence has been that such pieces have been worked by means of the chisel and the le, even in establishments where the ordinary planing-machine is used. There are also opl erations to be performed on large masses of metal, such as the cutting of grooves or recesses for the seats of keys, and for other purposes which have now to be effected by the cold-chisel, but which by the aid of my portable instrument may be cut in a more perfect manner and much more rapidly than by hand.

In the accompanying drawings, Figure lis a perspective representation of the whole machine. Fig. 2 is a side view of it, showing said machine as afiixed to a bench in such manner as that the planing-tool may be made to operate upon work held in the jaws of the common benchevise. Fig. 4 will serve to show how the instrument may be attached vto a large shaft for the purpose of cutting key' seats, &c.

In each of the figures where the `same parts are represented they are designated by the same letters of reference.

A is a bar, which 'is to be attached in a vertical position to a work-bench or to the article on which the planing-tool is intended to operate. This barhas its edges V-formed and made perfectly parallel to each other, so as to constitute slides for the' jaws B B, that are to receive the leaves of aipinion G on a shaft H, that may be turned by the winch I.

J is the tool-slide,the edges of which are received in V-grooves making. a part of the guide-plate K, that is solidly attached tothe Y slide F. To enable this plate to sustain the cutting-tool without springing, a bracket ory rib c is placed behind it. The tool-slide J is worked back and forth by'means of a screw L, that is turned by a winch M, which screwv works in a nut at the back of the slide and ina collar at a.

N is the tool, that is held by the hinged holdfast O in the4 same manner asin the .ordinary planing-machine, there not being anything new in this part.

The manner of using this machine will be obvious-to every competent machinist, the respective slides and the manner ofvv operating them enabling the workman to ladjust the toolito the work to be performed. When so adj usted, by turning the winch I the tool is' moved horizontally, and in its `forward mof tion will make a cut, and by reversing'thek motion the tool N will lift, and, being retractedwil1 be prepared to make another cut. If a vertical cut is required this maybe made by turning the winch E, the cutting-edge of the tool being properly formed for that purpose.

Having thus fully described the mannerin which I arrange the respective parts of my portable machine for planing metals, what I claim therein as new, and desire to secure by l Letters Patent, is Y i The particular manner in. which the slides and the apparatus for moving themA are ar-A ranged an'd combined with each other and withl the bar A, by which arrangement and combination said instrument is rendered portable and capableof being attached to a: yices. I therefore, as above stated, limit my Work-bench or to the work upon which it is claim to the particular combination herein set to operate. forth by which I have produced a tool which I do not make claim to either of the indiis substantially new and of great utility. vidu'al parts when taken alone, as of my invention, slides such as I have described, and Vitnesses: the giving motion to them by means of screws l A. L. ARCHAMBAULT, or of rack Smid pinions, being Well-known de- I. P. W'ALDEN. Y
